A given target offset may already have an environment associated with it (there can be multiple jumps to the same target). In that case we used to throw away the previous environment. With this CL we merge the environments instead.

On Android libraries there are zero length entries within the ranged symbols which break our range processing. This updates the logic to only add entries for zero-length entries if they aren't within the range of the previously added entry.

On Android we load the native library directly from the APK. As such, we need to convert symbols from the mapped APK to the underlying .so when symbolizing the ticks. This CL adds a --apk-embedded-library argument to tick processor to enable specifying which unstripped library file was embeded in the APK and enable symbolizing.

Seth Brenith authored
If we need to build an icu::UnicodeString for a string that is currently in one-byte representation, we first have to expand the string's content into a two-byte representation. Doing so involves allocating an array, which is slow. With this change, we can convert short strings on the stack instead to save time. The cutoff length for what counts as "short" is pretty arbitrary, but we believe many strings fit into an 80-column line. This increases the score of cdjs in JetStream 2 by 35% on my machine, because cdjs is basically a test of localeCompare throughput.

We currently have three different compresses that we thought it could be a good idea to merge into only one. Merging them would make sense since they all end up with the same code being generated. However, we would be losing knowing the MachineRepresentation in the cases of CompressSigned and Pointer.

This removes a special case from JSObject::WriteToField() where we didn't store anything in case of initializing a double field with the uninitialized sentinel. Instead we now store the hole NaN pattern there, as in other places. This makes it possible to do stricter checking in the TurboFan frontend when it comes to detecting bit patterns.

This is a quick fix for the recent bailout-on-uninitialized feature of the serializer, which does not work with resumables. For now, simply treat the ResumeGenerator bytecode as if it was an exception handler entry point.

Win64 unwind data can specify a language-specific handler function which is called as part of the search for an exception handler, as described in https://docs.microsoft.com/en-us/cpp/build/exception-handling-x64?view=vs-2019. This is used for example by Crashpad to register its own exception handler for exceptions in V8-generated code. There is a problem in the code that may cause a freeze on abort: in file \deps\v8\src\unwinding-info-win64.cc in function CRASH_HANDLER_FUNCTION_NAME the line: return EXCEPTION_CONTINUE_SEARCH; should be return ExceptionContinueSearch; These constants are both used in the context of Win32 exception handlers, but they have different semantics and unfortunately different values: EXCEPTION_CONTINUE_SEARCH (=0) should be returned by an exception filter while a language-specific handler should return an EXCEPTION_DISPOSITION value, and more precisely ExceptionContinueSearch (=1) in this case.
